Search Terms:

Each term included by default. These advanced search rules may be included: • prefix term with intitle:, intags:, insummary:, or inembed: to search only that field • prefix term with minus (-) to exclude it • surround one or more terms with quotes (") to search for exactly that phrase • group multiple terms into a sub-query by surrounding them with parentheses ( and ) • append quotes with ~nn = terms may not be more than nn words apart • append quotes with /nn = at least nn of the terms must be found • use "or" vertical bar (|) so only one term on its left or right side is required • example: intitle:"abc def"~4 "ghi jkl mno"/2 -(yyy|zzz)
